Answer:
a = 2
Step-by-step explanation:
given x = - 1 is a zero then f(- 1) = 0 , that is
a(- 1)³ - (- 1)² - 1 + 4 = 0
- a - 1 - 1 + 4 = 0
- a + 2 = 0 ( subtract 2 from both sides )
- a = - 2 ( multiply both sides by - 1 )
a = 2

<em>the missing term is 5</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>12x² - 75 = </em>
<em>= 3(4x² - 25)</em>
<em><u>use formula</u></em><em> a² - b² = (a - b)(a + b)</em>
<em>= 3(2x - 5)(2x + 5)</em>
<em>= 3(2x + 5)(2x - 5) </em>
<em>the missing term is 5</em>
<em>Good luck !</em>
